Linear OA(9¹⁴⁴, 170, F₉, 90) (dual of [170, 26, 91]-code), using 2 times truncation based on linear OA(9¹⁴⁶, 172, F₉, 92) (dual of [172, 26, 93]-code), using

concatenation of two codes [i] based on
1. linear OA(81³⁰, 43, F₈₁, 30) (dual of [43, 13, 31]-code or 43-arc in PG(29,81)), using
  - discarding factors / shortening the dual code based on linear OA(81³⁰, 81, F₈₁, 30) (dual of [81, 51, 31]-code or 81-arc in PG(29,81)), using
    - Reedâ€“Solomon code RS(51,81) [i]
2. linear OA(9², 4, F₉, 2) (dual of [4, 2, 3]-code or 4-arc in PG(1,9)), using
  - discarding factors / shortening the dual code based on linear OA(9², 9, F₉, 2) (dual of [9, 7, 3]-code or 9-arc in PG(1,9)), using
    - Reedâ€“Solomon code RS(7,9) [i]
